【摘要】:巷道頂板的位移監(jiān)測(cè)是煤礦安全生產(chǎn)中的重要問題。論文以無線傳輸方式為主完成了巷道頂板離層在線監(jiān)測(cè)系統(tǒng),為巷道頂板支護(hù)工作提供了可靠的技術(shù)支持。 本課題設(shè)計(jì)的巷道頂板位移數(shù)據(jù)的采集與傳輸系統(tǒng),分為三個(gè)主要部分:頂板離層儀節(jié)點(diǎn)、通信分站及上位機(jī)。頂板離層儀節(jié)點(diǎn)在巷道內(nèi)每隔50m安裝一個(gè),定時(shí)采集頂板離層數(shù)據(jù),并且各個(gè)節(jié)點(diǎn)以接力方式通過ZigBee或485混合傳輸?shù)姆绞桨褦?shù)據(jù)傳送至通信分站;每條巷道配置一臺(tái)通信分站,存儲(chǔ)本巷道內(nèi)所有節(jié)點(diǎn)的離層數(shù)據(jù)并在本地顯示,同時(shí)也通過以太網(wǎng)或485的方式與上位機(jī)進(jìn)行數(shù)據(jù)通信;上位機(jī)匯集各巷道通信分站的離層數(shù)據(jù),進(jìn)行存儲(chǔ)、管理及分析。本系統(tǒng)中的頂板離層儀節(jié)點(diǎn)電源以電池為主,低功耗成為設(shè)計(jì)中的主要制約因素,我們?cè)O(shè)計(jì)了定時(shí)休眠與喚醒的同步通信機(jī)制,成為節(jié)能的主要措施。 實(shí)際工作中,每臺(tái)通信分站最多可以連接64臺(tái)頂板離層儀節(jié)點(diǎn),可以滿足3000m長的巷道頂板離層監(jiān)控需求。頂板離層儀節(jié)點(diǎn)的位移測(cè)量精度達(dá)到5mm以內(nèi),在經(jīng)過軟硬件協(xié)同的低功耗設(shè)計(jì)后,平均每天的耗電量僅為2.63mAh,配備一顆2.4Ah鋰電池供電,,使用時(shí)間可達(dá)1年。本課題設(shè)計(jì)的巷道頂板位移監(jiān)測(cè)系統(tǒng)通過了重慶煤炭科學(xué)研究院的產(chǎn)品認(rèn)證,目前已經(jīng)在山西四候煤礦和王莊煤礦得到了應(yīng)用。
[Abstract]:Displacement monitoring of roadway roof is an important problem in coal mine safety production. In this paper, wireless transmission is the main way to complete the online monitoring system of roadway roof separation, which provides reliable technical support for roadway roof support. The data acquisition and transmission system of roadway roof displacement is divided into three main parts: the node of roof separation device, the communication sub-station and the upper computer. Every 50 meters in the roadway, the node of the roof seperator collects the data of the roof layer at a fixed time, and each node transmits the data to the communication sub-station by ZigBee or 485 by way of relay, and each roadway is provided with a communication sub-station, The data of all the nodes in the roadway are stored and displayed locally. At the same time, the data communication with the host computer is carried out by Ethernet or 485. The upper computer collects the data of each roadway communication sub-station for storage, management and analysis. In this system, battery is the main power supply in the roof layer separation device, and low power consumption is the main restriction factor in the design. We have designed the synchronous communication mechanism of timing dormancy and wake-up, which has become the main measure of energy saving. In practice, each communication sub-station can connect up to 64 roof dissociator nodes, which can meet the monitoring requirement of roadway roof separation layer with a length of 3000 m. The displacement measurement accuracy of the top layer separation device is within 5mm. After the low power design of software and hardware cooperation, the average daily power consumption is only 2.63 mAh. it is powered by a 2.4Ah lithium battery, and the service time can be up to one year. The roadway roof displacement monitoring system designed in this paper has passed the product certification of Chongqing Coal Science Research Institute and has been applied in Shanxi Sihui Coal Mine and Wangzhuang Coal Mine.
